D) ATP
Adenosine triphosphate (ATP) is known to be a complex organic compound that functions by providing energy to drive many biological processes in living cells. The building blocks of ATP is made up of Adenine, ribose sugar and three molecules of phosphate group. Furthermore, ATP is a molecular unit currency of intracellular energy transfer and large amount of energy is released during its hydrolysis.
 
        
                    
             
        
        
        
The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

Answer: i think the answer would be proteins, but please dont kill me if it isnt :( im in midle school so we recently covered this.
Explanation
heres the deal 
dna- transcribed to rna example: AGT- UCA, then you trabslate it, which then turns into specific proteins after being coded by codons (3 nucleotides put together.) hope this helps!
think nucleotide= A or G or C or T
CODES: A codes for T 
C 4 G
in RNA, Thymine (T) codes for Uracil (U)
